<ul><li>Amount of force used </li></ul><ul><li>· slight force…… nil…………….. in murder </li></ul><ul><li>· moderate force and considerable force….. 99%........ in murder </li></ul><ul><li>· great force ……..1%............ in murder </li></ul><ul><li> </li></ul><ul><li>Intention to kill </li></ul><ul><li>· nature of injury </li></ul><ul><li>· nature of weapon used </li></ul><ul><li>· site of election--choice of vital area </li></ul><ul><li>· number of wounds--private defence/vengeful homicide </li></ul><ul><li>· amount of force </li></ul>January 10, 2012 dr.smmn's lecture

<ul><li>The finding of spermatozoa in the female vaginal tract is indicative of recent sexual intercourse and this can be determined only by medical examination. </li></ul><ul><li>Rape---sexual intercourse / penetration / signs of struggle / age 13-14 </li></ul><ul><li>AGE </li></ul><ul><li>rk'def;rSKrSm yifw&m;cGifü vljydef;rsm; oufaorxlekdifaom jyXmef;csufrSm - rdef;ru tvkdwl onf jzpfap - rwlonfjzpfap xkdrdef;ronf touf (14) eSpfatmuf jzpfvQif? touf (13) eSpf atmuf r[kwfaom rdrdr,m;eSifh umrpyf,SufvQif rk'def;rSK rajrmuf[k qkd&mü touf eSifh ywfoufvmvQif aq;ynmuom tqHk;tjzwf ay;ekdifonf/ </li></ul><ul><li>(signs of struggle-she must struggle to the uttermost and to the last) </li></ul>January 10, 2012 dr.smmn's lecture
18.
<ul><li>In Grievous hurt (Section 320) </li></ul><ul><li>It is grievous hurt if there is a fracture or dislocation of a bone or tooth. Medical examination will be required for the diagnosis of fracture or dislocation. </li></ul>January 10, 2012 dr.smmn's lecture
19.
<ul><li>2. Used as a piece of circumstantial evidence </li></ul><ul><li>Circumstantial evidence (oG,f0dkufaom ywf0ef;usif oufao) </li></ul><ul><li>It is not a fact actually in issue but it is relevant to a fact actually in issue. </li></ul><ul><li>Circumstantial evidence must form an unbroken chain. To be of legal value, medical or forensic knowledge has to be used, for instance, in determining the blood stains on the clothing or on the weapon. In a case where there is no eyewitness, circumstantial evidence becomes the missing link along the chain of events in incriminating the accused. </li></ul>January 10, 2012 dr.smmn's lecture
25.
<ul><li>3. To check the correctness or relevancy of the statement of a witness </li></ul><ul><li> </li></ul><ul><li>In law courts, there is always conflicting statements from the witness of opposing parties. The opinion of the medical officer will be required by the law courts with regards to: - </li></ul><ul><li>(a) Reconstruction of a road traffic accident </li></ul><ul><li>An imprint abrasion will indicate the direction of the car hitting a pedestrian </li></ul><ul><li>(b) Time of infliction of a wound </li></ul><ul><li>Changes in colour and appearance in a bruise following an injury will indicate when the blow was inflicted </li></ul>January 10, 2012 dr.smmn's lecture
26.
<ul><li>(c) Signs of struggle in a case of alleged rape </li></ul><ul><li>Scratches, bruises and other injuries on the face, breasts, back and inner side of the thigh of a woman will support the statement that the sexual act was done against her will. </li></ul><ul><li>(d) The kind of weapon used </li></ul><ul><li>A lacerated wound is inflicted by a blunt weapon, while an incised wound is inflicted by a sharp edged weapon. </li></ul><ul><li>(e) The position of victim and assailant </li></ul><ul><li>Wounds on the back showed that the victim was attacked from behind and a defence wound will indicate that the victim was aware of an attack. </li></ul>January 10, 2012 dr.smmn's lecture
27.
<ul><li>4. To help in differentiating Accident, Suicide and Homicide </li></ul><ul><li> </li></ul><ul><li>In cases of deaths where there is no eye witness, as in a dead body found in a field, or in a room, or on a railway track, or recovered from the river, detailed examination of a body and the scene of crime is required in differentiating between accident, suicide and homicide. </li></ul><ul><li>The opinion of the medical officer will be very helpful for the investigating police officer and it may serve as a starting point for police investigation. </li></ul>January 10, 2012 dr.smmn's lecture
28.
<ul><li>A dead body, with multiple crushed injuries, found on the railway track, will be first assumed to be an accident. On post-mortem examination, fatal stab wounds may be found indicating a homicide. </li></ul><ul><li>Persons killed are sometimes thrown into the river to conceal the crime. Detailed post-mortem examination will reveal the actual cause of death. The presence of a classical suicidal cutthroat wound indicates death by suicide. </li></ul>January 10, 2012 dr.smmn's lecture
29.
<ul><li>5. Personal identification of unknown cases </li></ul><ul><li> </li></ul><ul><li>Personal identification is difficult in cases of: - </li></ul><ul><li>Skeletal remains – An old fracture or a deformity will be helpful in identifying the body. </li></ul><ul><li>Decomposed bodies – A scar, a tattoo mark on an amputated stump will be of considerable help in identifying the body. </li></ul><ul><li>Dismembered body – where the murderer wants to conceal the identity and cause of death of the victim. </li></ul>January 10, 2012 dr.smmn's lecture
30.
<ul><li>Severely burnt body – where dental data is very helpful in identification. </li></ul><ul><li>Victims of mass disaster – in air-crash, earthquake, burn conflagration </li></ul><ul><li>In personal identification of an unknown dead body, the knowledge of anatomy odontology, pathology, medicine, surgery, radiology, fingerprint (dactylography) anthropology, become very useful. </li></ul>January 10, 2012 dr.smmn's lecture
31.
<ul><li>6. To aid law enforcement forces </li></ul><ul><li>e.g., decomposition changes can be mistaken for assault and murder. </li></ul><ul><li>In sudden and unexplained deaths, a post-mortem examination may find out the medical cause of death and rule out any foul play. </li></ul>January 10, 2012 dr.smmn's lecture
32.
<ul><li>7. Other related roles of Forensic Medicine </li></ul><ul><li>Assessment of injuries for Third party insurance purpose, following an accident while using a motorised vehicle </li></ul><ul><li>Notification of industrial diseases accidents such as lead poisoning, arsenic poisoning, aniline poisoning, carbon tetra-chloride poisoning, and electrocutions for preventive measures. </li></ul>January 10, 2012 dr.smmn's lecture
33.
Departmental Objectives <ul><li>At the end of the course of instruction, the learner should be able to: - </li></ul><ul><li> </li></ul><ul><li>KNOWLEDGE </li></ul><ul><li>1. Have the knowledge of common medicolegal cases in Myanmar, and the principles of management of such cases </li></ul><ul><li>2. Correlate between the clinical manifestations and the autopsy findings. </li></ul><ul><li> </li></ul>January 10, 2012 dr.smmn's lecture
34.
<ul><li>SKILL </li></ul><ul><li>1. Serve as a competent medical witness in the law courts. </li></ul><ul><li>ATTITUDE </li></ul><ul><li>1. Have the knowledge and attitude to abide by the moral and legal codes of the ethical medical practice. </li></ul><ul><li>2. Have the awareness that it is one of the duties of a medical officer to assist law enforcement agencies and thereby help in the management of medicolegal problems of the community. </li></ul><ul><li>3. Be aware of the importance of consultation / referral to Specialist whenever necessary. </li></ul>January 10, 2012 dr.smmn's lecture
